Method and user equipment for transmitting uplink signal and user equipment for receiving uplink signal

An apparatus for a user equipment operating in a coverage enhancement mode in a wireless communication system, the apparatus comprising:

• at least one processor;
• and
• at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which;
• when executed, cause the at least one processor to perform operations comprising:
• transmitting a random access preamble on an uplink system band;
• receiving a random access response related to the random access preamble;
• and
• transmitting a first physical uplink shared channel (PUSCH) for carrying Msg3 based on the random access response,
• wherein the uplink system band comprises a plurality of uplink frequency bands in a frequency domain,
• wherein each of the plurality of uplink frequency bands includes only a predetermined number of consecutive resource blocks in the frequency domain,
• wherein the random access response includes frequency resource information for the first PUSCH,
• wherein the frequency resource information includes i) frequency band allocation information that designates an uplink frequency band from among the plurality of uplink frequency bands included in the uplink system band, and ii) resource allocation information that designates at least one resource block from among resource blocks included in the designated uplink frequency band, and
• wherein the first PUSCH is transmitted on the at least one resource block in the designated uplink frequency band.

A non-transitory computer-readable storage medium encoded with at least one computer program comprising instructions that, when executed by at least one processor, perform operations for a user equipment in a coverage enhancement mode to transmit an uplink channel in a wireless communication system, the operations comprising:

• transmitting a random access preamble on an uplink system band;
• receiving a random access response related to the random access preamble;
• and
• transmitting a first physical uplink shared channel (PUSCH) for carrying Msg3 based on the random access response,
• wherein the uplink system band comprises a plurality of uplink frequency bands in a frequency domain,
• wherein each of the plurality of uplink frequency bands includes only a predetermined number of consecutive resource blocks in the frequency domain,
• wherein the random access response includes frequency resource information for the first PUSCH,
• wherein the frequency resource information includes i) frequency band allocation information that designates an uplink frequency band from among the plurality of uplink frequency bands included in the uplink system band, and resource allocation information that designates at least one resource block from among resource blocks included in the designated uplink frequency band, and
• wherein the first PUSCH is transmitted on the at least one resource block in the designated uplink frequency band.
